🚀 Reactive Redis & Spring WebFlux – Personal Playground

📘 Overview

This is my personal project to explore and apply advanced concepts in Reactive Programming, focusing on the integration between Redis and Spring WebFlux. The goal is to enhance the performance, scalability, and real-time capability of Microservices using non-blocking techniques.

I created this repo as part of my self-learning journey in 2025, particularly after deep-diving into topics like caching, messaging, reactive Redis integration, and geospatial data handling.

🎯 Key Concepts Practiced

🔹 Caching with Redis

• Applied various Redis data structures (String, Hash, Set, Sorted Set, etc.)
• Implemented common caching patterns (Cache-Aside, Read-Through)
• Built a generic reactive cache utility
• Implemented cache TTL and eviction strategies

🔹 Reactive Redis Integration

• Used Spring Data Reactive Redis and Redisson with Spring Boot
• Built non-blocking cache access logic using Project Reactor
• Used Redis Streams and Pub/Sub in a reactive manner

🔹 Redis as Message Queue

• Simulated message queuing using Redis
• Built a priority queue
• Implemented Redis Pub/Sub for inter-service messaging

🔹 WebSocket + Redis Pub/Sub (Real-Time App)

• Developed a simple chat application
• WebSocket-based live messaging using Spring WebFlux
• Redis used to broadcast messages between connected clients

🔹 Geospatial Redis Use Case

• Built a restaurant locator using Redis’ geospatial data type
• Allowed location search based on zip code & radius

📊 Performance Testing

Using JMeter, I benchmarked some reactive endpoints and observed up to 80% improvement in throughput compared to traditional synchronous implementations.
